What's the difference between the different versions?
steadily increasing bandwidth allowing more video and audio info to pass through. Here's the wikipedia breakdown:
[edit] HDMI 1.0
Released December 2002.
Single-cable digital audio/video connection with a maximum bitrate of 4.9 Gbit/s. Supports up to 165 Mpixel/s video (1080p60 Hz or UXGA) and 8-channel/192 kHz/24-bit audio.
[edit] HDMI 1.1
Released May 2004.
Added support for DVD Audio.
[edit] HDMI 1.2
Released August 2005.
Added support for One Bit Audio, used on Super Audio CDs, up to 8 channels.
Availability of HDMI Type A connector for PC sources.
Ability for PC sources to use native RGB color-space while retaining the option to support the YCbCr CE color space.
Requirement for HDMI 1.2 and later displays to support low-voltage sources.
[edit] HDMI 1.2a
Released December 2005.
Fully specifies Consumer Electronic Control (CEC) features, command sets, and CEC compliance tests.
[edit] HDMI 1.3
Released 22 June 2006.[7][8]
Increases single-link bandwidth to 340 MHz (10.2 Gbit/s)
Optionally supports 30-bit, 36-bit, and 48-bit xvYCC, sRGB, or YCbCr with Deep Color up from 24-bit sRGB or YCbCr in previous HDMI versions. In terms of number of color combinations 24-bit allows for 16.7 million colors, 30-bit allows for 1 billion colors, 36-bit allows for 67 billion colors, and 48-bit allows for 281 trillion colors.
Incorporates automatic audio syncing (Audio video sync) capability.
Optionally supports output of Dolby TrueHD and DTS-HD Master Audio streams for external decoding by AV receivers.[9] TrueHD and DTS-HD are lossless audio codec formats used on Blu-ray Discs and HD DVDs. If the disc player can decode these streams into uncompressed audio, then HDMI 1.3 is not necessary, as all versions of HDMI can transport uncompressed audio.
Availability of a new Type C mini-connector for devices such as camcorders.[10]
[edit] HDMI 1.3a
Released 10 November 2006.[11]
Cable and Sink modifications for Type C
Source termination recommendation
Removed undershoot and maximum rise/fall time limits.
CEC capacitance limits changed
RGB video quantization range clarification
CEC commands for timer control brought back in an altered form, audio control commands added.
Concurrently released compliance test specification included.
